CUT-OUTn SPECIFICATION formingpart of Letters Patent No. 766,490, dated.August 2, 1904.

To all whoml it my concern:

Be it known that I, FERDINAND BUoHnor, a citizen of the United States,residing at the i city of NewYork, inthe borough of Brooklyn ldescription.

This invent-ion relates to electric cut-,outs`r l the object being` toprovidea simple and eompaci structure operated by a push-button orplunger and especially adapted for insertion in or combination with anincandesceutdainp socket, the cut-out being' used bv me in suoli alocation for the purpose of controllingv a tapcircnlt taken from themain circuit ol the socket; but it will be understood that the improvedcutout may be used under various conditionsand that the inventionresides iu the construction itself and not in any special combinationwith other devices or apparatus. .My im provci'l cut-out conipi'ises,essi`:ntially,

a lixed plate. opposite and parallel to which is arranged arotary diskcarrying on the surface i opposed to the plate a pair of contactsadapted when the disk is in one position to make contact with said plute and whenin another posia g tion to straddle said plate withoutmaking' cong tact therewith. The disk provided with a series ofratchet-teetli` and inunedialelv adioinl ing these and in a parallelrelation is a fiat plat-e actingr as a plunger by manual manipulation,said flat plate having' two dogs, one of which 1 is adapted to engageone of the ratchet-leeth i of the disk during the forward movement ofthe plunger, while. the other dog engages another of the ratchet-teethduring' the return movement of the plunger. gagements cause the disk tobe. rotated each 40 acne-eighth turn, so that a movement of the gplunger inward and outward rotates thedisk i a, quarter-turn and eithercompletes or breaks l the circuit between the disk and tixed plate.Auxiliary to these devices is a spring' comv bined and arranged in suchmanner as to keep the plunger to its work and ,vet permit g it to yieldto avoid interferiuiee with theI E ratchet-teeth during rotary motion ofthe disk.

The parte of my cut-out are housed within a block of hard rubber orother suitable inrifhis bioeh made in two part-s r and il. eachbeingsubstantially a disk having' a diamctrical raised portion acrossone face, thus leaving' a srgnncntai opene Fig'. i [sun edge view Fig. 8is a the joining' of the two disks. held together by bolts u". one oneach side ot' 'flfhe disks are ln the disk if there is an axial metalstud Z1, having' attached to its j uteren=1l a contact head and at its'inner end. a crosrelni-ad 12in the lorni ol" a plate, each rnd of v.hielt tor-shaped and olI .slightly less than ninetyde- This plate is afixture in noir# cular depression .'f and leaves open sectorshapedspar/es /f' at\' pp sile sides. lfiiis plate /fis a circuit terminal orcontact through whirh the current mai be ied to the head 1)' and to anextension Ji'- l'oi anydesired arrange ln the disk u." there is acontact-head c, exposed outside, which is attached to the end of anaxial screw c', around the head of which lits a rotaia` disk f, whichstands parallel to the fixed plate and concentric with the stud lf. Theupper surface of this disk c is provided at diainetrically'oppositepoints with two lugs i" if, shaped similar to ratchet-teeth,

'lhese teeth are adapted to make cont-act siuuiitancously with theopposite `Aends oi' the plate when the dish is rotated to bringl thisconnect-ion about; but when the disk is rotated ninety degrees from theposition of contact the lugs project engage the ratchet-teeth e2 on thedisk.

into the spaces b b", and thus break* the eircuit. The under side ofdisk e is provided with' four ratchet-teeth e2, arranged in a circle atthe outer edge of the disk and all pointing in the same direction.Immediately beneath the disk is a fiat plate f, serving as anoperating-plunger, said plate having a slot j", through which the screwc passes, and having two dogs f 2 and f3, extending upward on each sideof the slot and in a postiorjr1 ttio C plate f extends radially outwardthrough an opening in the side oi' the block A and carries at its outerend a push-button f. A spring g is provided between the head of thepushbutton and the block A, having a tendency to force the buttonoutward. Beneath the plate fis a disk upon the stud e', which disk isforced against platef by a springj, surrounding the stud c' for thepurpose of holding plate f up against disk so that its dogs f s and f3will engage with the ratchet-teeth. At the same time the disk is free totip in any direction, thus permitting the plate f to yield when theratchet-teeth of the disk e ride over the dogs of the plate, as will behereinafter described. It will be seen that when diskeand plate 712 arein contact a circuit is closed from Contact c through the stud c', diske, plate b2, from which it branches, one branch leading through the studto the button b and the other through the extension b5.

The operation is as follows: Referring more. particularly to Figs. 4 and5, it will be seen that the plunger f is extended outward in Fig. 4.'Ihis is the normal position, during which the circuit may lbe eitheropen or closed. We

will assume that at the present time the lugs e' of disk e are.Ioccupying the spaces b, the circuit being thus open. By pressing thepush-button f* and forcing the plunger inu ward the dog f engages with aratchet-tooth e2 and the disk is rotated one-eighth of a turn, duringwhich motion a ratchet-tooth e2 on the opposite side of the disk slidesover the dog f3 and assumes the position shown in Fig. 5, where the dogwill engage with its shoulder upon 4the return movement of the plunger.The plunger now being released, spring g acts` and forces it (outward,during which movement dog f3 aforesaid Aengages with ratchet-tooth e2and moves the disk another one-eighth turn in the same direction asbefore. This completes a quarter-turn of the disk and carries the twolugs e', respectively, into contact with the ends of the plate andcloses the circuit. it will be seen that dur- I plate in one direction.

ing the movement of the disk to carry the yield or tip. This ispermitted by the yielding support beneath the plate; It will ybe seenthat the to-and-fro excursion of the plunger completes either a make orvbreak of the circuit.

It is obvious that this structure may be used'also for a double-poleswitch by insulating the lugs e' from each other and insulating the endsof the plate b2 from each. My invention is therefore not limited inrespect to the number of circuits or lines controlled.

Having described my invention, I claim-- 1. In an electric cnt-out, thecombination with a fixed plate forming one terminal of the circuit, arotary plate arranged parallel thereto and adapted to make and breakIcontact therewith, in combination with-a' plunger 2. In a cut-out, thecombination of a fixed.

contact-plate, a rotary disk carrying contactpoints adapted to engageand discngage with the plate, ratchet-teeth arranged in aconcent'ric'crcle on said disk and a reciprocatory plunger provided withtwo dogs adapted to engagerespectively and alternately with ratchet-(tieelh o n opposite sides of the center of the v3. In a cut-eut, thecombination of a fixed contact-plate, a rotary disk carryingcontactpoints adapted to engage and disengage with the plate,ratchet-,teeth'arranged in a concentric circle on said disk, areciprocatory plunger provided with two dogs adapted to engagerespectively and alternately with ratchet-teeth 'on opposite sides ofthe center of the disk and aspring tending to hold the plunger inengagement with the ratchet-teeth.

4. The combination of the fixed contactplate b2, the rotarycontact-'disk e' having ratchet-teeth, a reciprocatory plate providedwith a slot through which the axis of the disk passes, two dogs carriedby said plate adapted to engage the ratchet-.teeth alternately and aspring adapted to move the reciprocatory In witness whereof` I subscribemy signature in presence 'of two witnesses.
